[AD7795] unused IOUT2


I would like to know unused pin termination.

When AIN5+ and AI5- use as IOUT1 and IOUT2.

The customer needs only IOUT1 with 1mA.

But according to data sheet IOUT2 seems cannot disable when output current is 1mA.

Is this unused IOUT2 should be connect to somewhere or OK to NC?

Thank you for your help as always.

Best regards,
